* \brief Milan v1.2 Section 5.4.2.25 / Tables 5.13–5.14 — AVB Interface counters.
* LINK_UP / LINK_DOWN / GPTP_GM_CHANGED are mandatory; controllers infer the
* current link state from (LINK_UP > LINK_DOWN). We don't (yet) hook netlink
* for runtime up/down events, so link_up is seeded to 1 at descriptor
* creation — the interface is up by the time the daemon successfully binds. */
